what is hypermetropia or farsightedness? What are the novih​

Answer 1

Explanation:

Mass= density x volume

Weight = Mass x Gravity= mg

Mass of any object will remain same on any planet just the value of g ( gravitation) will change .so weight will change

Eg: Let g= 10

mass of 1 st body (earth ) = 10

Weight(earth) = 100 kg(mxg)

On Mars let g= 6 then

Mass = 10

Weight (mars)= 10x6 = 60 (mg)
